What is energy??? We have a basic concept of energy as something we need to get work done. We don’t have a clue about what it is in a physical sense. The production of energy usually means we convert something that has dimensions and weight or mass into something that doesn’t have weight or mass or dimensions. For instance, we turn wood which has weight or mass and dimensions into heat which doesn’t have weight or mass or dimensions. You can feel the effects of heat but you can’t see heat except as it affects other things such as air. Time is something that doesn’t have weight or mass or dimensions even though it affects all of us. Gravitons don’t appear to have weight or mass or dimensions because Gravitons are the only source of gravity. If they had weight or mass or dimensions something else would have to supply gravity. Protons don’t have weight or mass or dimensions because they need to travel constantly at the speed of light which requires all their mass to be converted to energy. Energy, therefore, is something that doesn’t have weight or mass or dimensions but is detectable because of its’ influence on other things.
